Solid biofuels - Determination of moisture content - Part 2: Simplified method (ISO 18134‑2:2024)
This document specifies a method of determining the moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine production control on site. The method described in this document is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis).
NOTE Biomass materials can contain small amounts of volatile organic compounds (VOC) which can evaporate when determining moisture content by oven drying (see References [1] and [2]). The release of such compounds is quite small relative to the overall moisture content as determined by this method and is disregarded in this document.
Biogene Festbrennstoffe - Bestimmung des Wassergehaltes - Teil 2: Vereinfachtes Verfahren (ISO 18134‑2:2024)
Dieses Dokument legt das Verfahren zur Bestimmung des Wassergehaltes einer Versuchsprobe von biogenen Festbrennstoffen durch Trocknen in einem Ofen fest und wird angewendet, wenn nicht die höchste Präzision erforderlich ist, z. B. zur routinemäßigen Produktionskontrolle im Betrieb. Das in diesem Dokument beschriebene Verfahren ist auf alle biogenen Festbrennstoffe anwendbar. Der Wassergehalt von biogenen Festbrennstoffen (im Anlieferungszustand) wird immer bezogen auf die Gesamtmasse der Versuchsprobe (Bezugsbasis Feuchtmasse) angegeben.
ANMERKUNG Biomassematerialien können geringe Mengen an flüchtigen organischen Verbindungen (VOC, en: volatile organic compounds) enthalten, die bei der Bestimmung des Wassergehaltes durch Ofentrocknung verdampfen können (siehe Literaturhinweise [1] und [2]). Die Freisetzung derartiger Verbindungen ist im Verhältnis zum Gesamtgehalt an Wasser, der mit diesem Verfahren bestimmt wird, verhältnismäßig gering und wird in diesem Dokument vernachlässigt.
Biocombustibles solides - Dosage de la teneur en humidité - Partie 2: Méthode simplifiée (ISO 18134‑2:2024)
Le présent document spécifie une méthode de détermination de la teneur en humidité d’un échantillon pour essai de biocombustibles solides par séchage à l’étuve. Cette méthode est utilisée lorsque la fidélité maximale n’est pas nécessaire, par exemple, pour un contrôle de routine de la production in situ. La méthode décrite dans le présent document est applicable à l’ensemble des biocombustibles solides. La teneur en humidité des biocombustibles solides (à réception) est toujours rapportée à la masse totale de l'échantillon pour essai (base humide).
NOTE Les matériaux de la biomasse peuvent contenir de petites quantités de composés organiques volatils (COV) qui peuvent s'évaporer lors du dosage de la teneur en humidité par séchage à l’étuve (voir Références [1] et [2]). La libération de ces composés est très faible par rapport à la teneur en humidité globale telle que déterminée par cette méthode et n'est pas prise en compte dans le présent document.
Trdna biogoriva - Določanje vlage - 2. del: Poenostavljena metoda (ISO 18134-2:2024)
Standard ISO 18134-2:2017 opisuje metodo določanja celotne vlage v preskusnem vzorcu trdnih biogoriv s sušenjem v peči in se uporablja, kadar pri določanju vlage ni potrebna najvišja raven natančnosti (npr. pri rutinski kontroli proizvodnje na mestu uporabe). Metoda, opisana v standardu ISO 18134 (vsi deli), se uporablja za vsa trdna biogoriva. Navedena vsebnost vlage v trdnih biogorivih (pri dobavi) vedno temelji na skupni masi preskusnega vzorca (mokra osnova).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
